WATERHEATER.

SPECIFICATION forming part of Letters Patent No. 544,353, dated August13, 1895.

Application filed May 29, 1894. Serial No. 512,923. (No model.)

To @ZZ whom it may concern): A

Be it known that I, EUGENE G. GOODWIN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Water-Heaters; and I dohereby declarethe following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to a novel construction and arrangement in awater-heater, the object being to providea water-heater, adapted moreespecially for use in houses, that will furnish a supply of hot water tothe hot-Water tank without the employment of the waterback, but inconnection with a gas or oil burner, or with the hot-Water or steamheating system of the house.

In employing my system for heating water, the hot-water tank can beconnected in the usual way with the water-back of the range, if desired,and may at the .same time have the water-heater in communication withthe hot-water or steam heating system of the building, and also besupplied with a burner, according to the arrangement preferred, and Iwill point out hereinafter the specific construction of the parts andthe ways in which it can be employed. Y

The invention consists in the features of construction and combinationand arrangement of parts hereinafter fully described and specicallyclaimed.

In the accompanying drawings, Figure l is a vertical sectional view of awater-heater constructed in accordance with my invention and ahot-watertank communicating there with. Fig. 2 is a horizontal sectional view ofthe water-heater on an enlarged scale and taken on the line 2 2 of Fig.5. Fig. 3 is a horizontal sectional view on the line 3 3 of Fig. 5. Fig.4 is a horizontal sectional View taken on the line4 4 of Fig. 5. Fig. 5is a central vertical section of the water-heater, taken on the line 5 5of Figs. 2, 3, and 4.

Referring now to said drawings, A indi- Cates, as a whole, thewater-heater, and B the hot-water tank, 'said hot-water tank B being offamiliar construction. The said waterheater A is provided with awater-inlet pipe 1 leading from a Water-main or other supply,

and is located at the lower end of the waterheater. From thissupply-pipe 1 the water enters the heater, is heated therein, and passesott' through theoutlet-pipe 2 thatleads to the inlet-port 3 at the upperend of the water-tank B, and communicates also with the hot-water-supplypipe 4 of the building. The hot-water tank B is provided at its lowerend with an outlet-pipe 5 that communicates also with the lower endofthe heaterA through a pipe 6.

In a system for heating water, as above described, the water will enterthrough the pipe 1, pass up through the pipe 2, and circulate throughthe hot-water-tank pipes 5 and 6,

and so on, or pass oft through the hot-watersupply pipe 4 in an obviousmanner.

I will now proceed to describe the particular construction of saidwater-heater A. The said Water-heater A is divided into two principal'parts-namely, the heating-drum 7 and the'heater 8f The saidheating-drum is einployed for heating the water by means of burnersemploying gas or oil, while the heater 8 is employed for heating thewater by means of the hot-water or steam system of the building,although I have arranged it that said burner may also act in connectionwith the heater 8. The cold -water supply enters the heatingdrum7,saidheating-drum communicates at itsV` upper end with the lower end of awater-receptacle or second chamber 16, and the upper end of the saidsecond chamber 16 communicates with the pipe 2, leading from the upperend of the hea/ter. The heating-drum 7 is preferably cylindrical andissuitablysupported by a stand 9 orin any other convenient manner. Saiddrum 7 is provided conveniently at diametrically-opposite points withthe ports 10 and 11. Thesaid heating-drum is provided on its upper sideand about its center with a port 12 and is provided at its peripherywith a shoulder 13, upon which rests the outer casing or chamber.(Indicated by 14.) Beneath the heating-drum 7 is a suitable burner ofany approved construction, (indicated by 15,) in

which gas or oil can be burned for heating the said drum. Located withinthe casing or chamber 14 of the heater is the water-receptacle or secondchamber 1G, consisting, preferably, offour hollow wings 17, Whose wallsjoin each other, so that said water-'receptacle IOO 1G in cross-sectionhas the form of a cross. The said water-receptacle 16 tits within thecasing 14 and is provided at its lower end, at about its center, with aport 1S, by means of which communication between the heatingdrum andsaid water-receptacle is established by a nipple 19, as clearly shown inFig. 5. At the upper end of the water-receptacle 1G the. spaces betweenthe walls of the hollow wings are open, while extending between thewalls of each hollow wing and the adjacent wall of thehollow wingatright angles thereto is a partition, web, or closure 20, Figs. 2 and4. The saidwebs are at an incline for draining off the water, should theheater be empty, and at the upper and outer endjoin a iiat ring 21, thatextends around the entire waterheater, although cut out at the pointsmarked The upper end of the casing 14 is pro'- vided with an'inwardly-turned tiange 23 to encounter the ring 21, and then a suitablepacking or gasket 24 is placed between the ring 21 and flange 23. Uponthe upper end ot the casing 14 is located a top plate or hood 25,between which and the iiange 23 of the casing a packing or gasket ring26 is placed, and the hood-flange 23 and ring 2l are firmly boltedtogether by means of bolts 27. The pipe 2 communicates with the interiorof the water-receptacle 1G through the port 2S in the hood 25, as shownin Fig. 5.

The heater 8 for heating the water within the receptacle 16 is of thesame general form as said water-receptacle-that is to say, it has thehollow wings 30 located at right angles, but is entirely closed at itsupper and lower ends. The said heater 8 tits within the water-receptacle16 and in the sides of one of its wings has the ports 31 and 32, throughwhich communication is established between said heater 8 and thehzt-,waterror steam heating system of the building by means of the pipes33 and 34, which pass lthrough the adjacent walls of the casing 14 andwings 17 and have tight joints with said ports 3l and 32.

As a further and separate improvement I have arranged so that the burner15 will not only heat the water as it passes through the drum 7, butwill also attack the sides of the wings 17 of the water-receptacle. Forthis purpose I arrange four passages 35 through the drum at pointsbetween the wings of the water receptacle, said passages 35 being formedby vertical walls 3G extending between the upper and lower sides of saiddrum 7. Near the upper end of the casing 14, as shown in Figs. 3 and 5,and between the wings 17 of the water-receptacle, are a series ofopenings 37 for the escape of the products ot' combustion. It will beseen that the relative contour of the casing 14 and water-receptacle orsecond chamber 16 is such that tlues are formed between the said parts.

1 will now proceed to describe the manner in which said water-heater isused. For instance, it may be that the heater is in communication withthe water-back and with the hot-water and steam heating system of thebuilding, or both, and is also provided with the burner 15. In thesummer time, or at other times when the heating system of the house isnot in use, or when there is no fire in the range, a supply of hot watercan be easily obtained by lighting the burner 15, which will heatthcwater in the tank and in the drum in an obvious manner and raise thetemperature iurther, by reason of the heat passing up through thepassages or flues 35, and supply the watertank B with hot water, whichmay be drawn oft in the usual manner. Again, the water can be heated byallowing the steam or hot water of the heating system of the building topass through the heater 8, causing the cireulation aforesaid, whether inconnection or not with the water-back or the burner. In the cases abovealluded to it is assumed that the water-supply has been through the pipe1 entering the drum, but it is to be noted that said water-supply can beobtained through the pipe 38, (shown in dotted lines in Fig. 1,) inwhich case said port 10 would be closed, or if the pipe l were used inthe system in other relations, a cock 0r valve 39, (shown in dottedlines in Fig. 1,) could be closed.

It is manifest from the above description that I provide a water-heaterfor a building that can be applied without disarranging or altering thehot-water tank already in place, or the water-heater system heretoforeemployed, or, on the other hand, it can be applied as a separate system,and in either case will work with the same eticiency; and it is to benoted that even when applied in connection with these other systems itis unnecessary to change or disarrange them, as they may work separatelyor in connection with each other.

The apparatus is simple and inexpensive and can be applied at a smallcost, and at the same time increases the eiticiency and capabilities ofthe water-heating system ot a building.

I claim- 1. The combination with an outer chamber provided with anoutlet port at one end, a second chamber within said outer chamber withits end situated adjacent to the said outlet port conforming to thecontour of said outer chamber so as to make a water tight jointtherewith, an inlet port at the other end of said second chamber, saidouter and second chambers being shaped to form iiues between theirwalls, and a heater situated within said second chamber, 'substantiallyas described.
